Software Engineer, Mobile, Web3

About the role

The position is centered on designing intake workflows for mobile Web3 features, translating user research findings and market signals into precise product specifications that guide development. The role requires transforming qualitative insights into actionable documentation that defines scope, behavior, and interaction models for upcoming mobile capabilities. The engineer will map detailed user journeys, identify critical edge cases, and produce clear artifacts that direct engineering execution while balancing opportunity with operational constraints. Another core duty involves architecting build components for secure key management and transaction handling, ensuring system reliability under heavy blockchain related loads. This work focuses on constructing foundational modules that protect private keys and reliably process onchain actions while adhering to strict security and Web3 standards. The role also coordinates review cycles with product and security stakeholders, iteratively refining code and documentation to satisfy compliance requirements and internal quality benchmarks. Engineers must ship iterative updates to production environments, monitor performance indicators and user feedback, and use these observations to drive subsequent improvements in functionality and reliability. A key responsibility includes partnering with growth and compliance teams to align feature launches with regional regulations and market expansion strategies across different jurisdictions. The position further involves verifying that every requirement matches current operational needs, particularly regarding support for Web3 protocols, trading capabilities, and seamless wallet integration. Finally, the role confirms that implementation robustly handles scale and edge cases, with rigorous attention to performance, security, and end user experience under demanding conditions.
